To all whom may concern.' I

citizen otthevUnited States, and a resident oi Salisbury, in the county or Rowan and` State of North Carolina havejinyented ag,

new and-useful improverrr-nitr in Sewerage lfisposal Tanks, oi which the following yis a specification.. i A f i y '-,f My invention relates to sewerage disposal tanks for use in communitiesnot equippedf "e: ththeinodern sewerage disposal systems.'

in tanks of this character or what are usually known as septic tanks a. plurality ot communicating tanks orseparate chambers are employed wherein the human excrement passes tin-onge the several tanks or coinpartments and inveach is subjected to bacterial action and is finally permitted to 'd ain in the ground in a purilied liquid state. The main object 'to tanks oi' this character is that ooeor,n1ore tank compartments settles or sinks deeper in its foundation which obviously throws the pipes eonnectinglv the tanks together out of alinement which cracks the pipes or causes leaky `ioints.v it

' the cracked pipesor broken joints will pass into the ground and thereby contaminating the sanieand'rendering unsa-nitary conditions.

llilith theselob'iections in mind it is the primary purpose of my'invention to provide a sewerage disposal tank including plurality of compartments or chambers all of which are positively locked 'together and thereby@ makingl it impossible for relative inovenaenL 'of the individual chambers or coinpartin s.

lt is a further object .of the invention to provide'a sewerage disposal tank eminulyingjr a plurality or' chambers or compartments which Will be placed in coinciding relation in the ground and cemented or united in a novel manner.

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of eienient-s,` construction and arrangement of parts and operations to be hereinafter more folly described, claimed and illustratedin the accompanying drawings wher-ein,

As is illustrated in the drawings thev tank is substantially cylindrical, and isiormed at one side with a flat or straight wall T so that two tanks may be arranged in mat-ingr relation as shown in Fig. 2. 'lheoutcr tace of each 'all is provided with dore-tail channels or grooves Sv'and the grooves or channels `ot one fiattene-:l Wall registered coincident with the Igrooves of the other Wall, thereby providingr longitudinal keywrays 9 in which cement or the like is poured to provide a bond or key 'or compartment 5 and. located at diametriv cally opposite pointsare semrcircular Walls 'il which extend from the upper end ot the tanks or sections to a point below the surtaceo the liquid contained in these tanks. As is shown in Fig. 2. the tanks are arranged so that one pair oi walls ll are adjacenteach other and communicatingr with -these compartments or chambers at these points is a short pipe connection An inlet pipe 13 leads to one of the compart ments or chambers 5 at a point- Where the other wall 11 is disposed and extendingfrom the other compartment'- or chamber 5 at a point Where its Wall vil is disposed is an outlet pipe 1+i which extends to a suitable drain bed. These Walls il in addition to directing: the passage of the sewage through the mnipartments serve to brace or reinforce the sections.

In use it will be obvious that the sewage passiner through the pipeA 13 Awill. pass into the first chamber or corniiartlnent 5 where it is subjected to bacterial action and thence through the pipe l2 and discharged into the'l other compartment or chamber 5 where it is subjected to further bacterial action and the decomposition of all foreign matter., From this point the sewage is let off to the drain bed through the pipe 14 in a purified liquid state.

It is to be understood thatthe form of my invention herein shown and -described is to be taken as a preferred-exampleof the same,

, and that various changes in the shape, sizel -10 and arrangement of parte may be resorted to without departingfrom the spirit of the invention or. the scopefofthe ysubjoined claims. fl Having thus` described my invention, what l claim as v`vnew and desire to secure and protect by Letters Patent ofthe United States isz-1 a 1. An apparatus of the character described comprising a plurality of chambers, each having a flattened face and adapted to be buriedfunthe ground with the attened faces abutting each other, the flattened faces being provided with vertically disposed regsterlng grooves, and a plastic bond filling the grooves whereby to prevent one chamber from sinking with respect to the other the flattened ends serving to reinforce each other.

2. In a' sewerage tank, a plurality of Achambers each provided with a flattened WALTER P. HOOKER.
